# ROX eclass Version 2

# This eclass was created by Sergey Kuleshov (svyatogor@gentoo.org) and
# Alexander Simonov (devil@gentoo.org.ua) to ease installation of ROX desktop
# applications. Enhancements and python additions by Peter Hyman.
# Small fixes and current maintenance by the Rox herd (rox@gentoo.org)

# These variables are used in the GLOBAL scope to decide on DEPENDs, so they
# must be set BEFORE you 'inherit rox':
#
# ROX_VER - the minimum version of rox filer required. Default is 2.1.0
# ROX_LIB_VER - version of rox-lib required if any
# ROX_CLIB_VER - version of rox-clib required if any
#
# These variables are only used in local scopes, and so may be set anywhere in
# the ebuild:
#
# APPNAME - the actual name of the application as the app folder is named
# WRAPPERNAME - the name of the wrapper installed into /usr/bin
#    Defaults to 'rox-${PN}', or just ${PN} if it already starts with 'rox'.
#    This does not normally need to be overridden.
#    If overridden with the reserved word 'skip' no wrapper will be created.
# APPNAME_COLLISION - If not set, the old naming convention for wrappers of
#    /usr/bin/${APPNAME} will still be around.  Needs only be set in packages
#    with known collisions (such as Pager, which collides with afterstep)
# APPCATEGORY - the .desktop categories this application should be placed in.
#    If unset, no .desktop file will be created.  For a list of acceptable
#    category names, see
#    http://standards.freedesktop.org/menu-spec/latest/apa.html
# KEEP_SRC - this flag, if set, will not remove the source directory
#    but will do a make clean in it. This is useful if users wish to
#    preserve the source code for some reason

# For examples refer to ebuilds in rox-extra/ or rox-base/

# need python to byte compile modules, if any
# need autotools to run autoreconf, if required
inherit python autotools eutils multilib
